Design Front Page Image/Banner

I need three images designed for the front page of a site. The image is basically a large banner. It should be an image(theme will be provided) with text and a search feature. Should be fairly easy job for a good designer. I MUST SEE AN MOCKUP BEFORE AWARDING THE PROJECT. You can add watermarks to protect the work. Please PM me for additional details. I will award the project and escrow the funds once you have submitted a acceptable design. The budget is $30...I am willing to pay a higher amount than usual because I need these done within 6-8 hours max.
